Operación de planta piloto hibrida UASB +SMEBR para eliminación de contaminantes Emergentes.

Abstract

This research was aimed to evaluate the start-up and operation of a hybrid UASB+ SMEBR system. Elimination of COD (organic matter) and nutrients (NT, PT, NH4) was controlled variables along the experiment. The elimination of emerging contaminants drug type (Ibuprofen, Diclofenac) have been also studied. With this propose, electrocoagulation with current densities of 5.10 and 15A/m2 and operating times of 5minON/10minOFF was analyzed.

The global system achieved removals of 98%, 76% and 30% for COD, Ammonium and NT respectively. By other hand the elimination of PT was reached 98% in the SMBR, which also showed an improvement in fouling reduction. A reduction of 36% of soluble EPS (proteins) was registered, while ibuprofen and Diclofenac eliminations were in the rank of 94% and 98%.
